2.1 Classification of hazards

3 / 08 / 2006

We classify the safety warnings into various levels. The table below gives an overview of theclassification of symbols (pictograms) and warnings for the specific danger and its (possible)consequences.

Picto-gram

Alarm expres-sion Definition/Consequences

Danger! Imminent danger that will cause serious injury or death to personal.

WARNING! Risk: A danger that might cause serious injury or death to personal.

CAUTION! Danger of unsafe procedure that might cause injury to personal or damage to property.

ATTENTION!

Situation that could cause damage to the machine and product and other types of damage.No risk of injury to personal.

INFORMATION

Application tips and other important or useful information and notes.No dangerous or harmful consequences for personal or objects.

In the case of specific dangers, we replace the pictogram by

2.2 Proper use

Page 6

WARNING!

In the event of improper use of the add-on pieces, it• will endanger the user,• will endanger the machine and other material property of the operator or user,• may affect proper operation of the machine.The add-on pieces as conversion kit are provided for the computer-aided - CNC, ComputerisedNumerical Control - milling operations of your machine.

The drive of the step motors may also be performed manually with a control unit(potentiometer).

Improperuse!

The milling machine with the adapter kit must only be placed and operated in dry and ventilatedrooms.

The hand wheels need to be disassembled.

If the adapter kit is used in any way other than described above or modified without approval ofthe company Optimum Maschinen Germany GmbH the adapter kit is no longer properly used.

We do not take liability for any damage caused by improper use.

We would like to stress that any modifications to the construction, or technical or technologicalmodifications that have not been authorised by Optimum Maschinen GmbH will also render theguarantee null and void.

Means of shaft lock-down device "Loctite 648, join the shaft".The designation of the parts in the assembly description corresponds to the numbering of the packing list.In order to degrease the shaft, a cleaner for brakes or a corresponding cleaning agent is required.A tenacious grease e.g. Mobilux 3 or a corresponding lubricating grease serves to grease the bearings.

Required tools:

lubricating oil for thread cutting, twist drill 5mm, counter sink; screw tap M6, manual drilling machine, calliper gauge,a set of Allen keys, set of fork wrenches, blow-back proof plastic tip hammer,box wrench 13mm, screw driver, tongs, chipping spanner,soldering iron with accessories, abrasive cloth, small chisel (you may also use a small screw driver).

5 Assembly and maintenance instruction ball bearing spindle

03 / 08 / 2006

Ball bearing spindle foot nuts without strippers)

The delivery of the ball bearing nut with assembly bushing (ready-for-assembly) as well as thespindle are corrosion resistant. The ball screws are not mounted.

The ball screws are precision parts and need to be handled with cleanness and care.

The ball nut is packed ready for assembly.

Please take the ball bearing spindle off the packing only directly before assembly.

5.1 Assembly
Thoroughly clean the spindle up to the groove of the thread.
Remove the retaining ring on the side of the assembly bushing which is not displaced.

Push the nut with the assembly bushing over the treated shaft end (concentrically put on the spindle axis, refer to the illustration) and push it carefully and completely onto the spindle. Remove the assembly bushing only after having completed the assembly.

Adjust the clearing between the nut and the spindle with the adjusting screw (refer to the illustration). It should be possible to move the spindle slightly into both directions. Check the clearing at several points along the whole length of the spindle by holding the spindle and moving the nut axially; there must be no clearance (the axial clearance will be atteined before the radial clamping).

Page 24Ball bearing spindle assembly and maintenance instruction ; Version 1.4.7

Assembly and maintenance instruction ball bearing spindleOPTIMUMM A S C H I N E N - G E R M A N Y

5.2 Installation with spindle

Page 25

The ball bearing spindle needs to be installed radial and without tension: When you tighten thebearing, the slide needs to be moved on the corresponding side to and fro.

5.3 Lubricating notes
Before commissioning, imperatively lubricate the spindle on the complete length of the threadwith the help of the nut .
You may use common oils and greases for ball bearings (soda soap greases) as lubricant. Butplease avoid lubricants with additives such as graphite and MOS.

Due to the axial movement between nut and spindle the loss of lubricant is higher than for ballbearings so that it is not possible to have it lubricated for life time.

Oil viscosity classes according to DIN 51517 T3

CLP ISO-VG for spindle Ø 16mm

Average speed [ min-1 ] Recommended SO viscosity class at 40 ° C

Required viscosity at operating tem-peratures of about 30 °C (cST)

20 ISO VG 460 about 875





Oil lubrication

For higher speeds of the spindle ( >500 min-1 ) there is less heating up with oil lubrication thenwith grease. But the maintenance intervals will be reduced depending on the applications youshould lubricate every 40 to 60 operating hours.

Grease lubrication

The grease lubrication will offer the advantages of an independent installation position andlarger lubricating intervals (from 300 to 700 operating hours) up to a speed of about 800 min-1.

If possible, use soda soap lubricants KP 2 K according to DIN 51 825.

5.4 Protective measures

© 2006

Protect the lubricated ball screws from dust, chips.

CAUTION!If you do not press on the bushingwith enough force, the balls may falloff the nut. Then the nut becomesunserviceable!

Have the nut slide on the spindle.


CAUTION!

Please make sure that the machine faced side of the bushing is placed onto the spindle!

The nut has to run on the spindle by itself.

Turn the nut clockwise on the spindle. If the nut does not run smoothly, just turn it back and try again.

CAUTION!Do not force the nut downward, as itwould be destroyed!


INFORMATIONIf you need the lubricating nipple afterassembly at the other side of the nut,you have to remove the relief from thealuminium bushing.

Place the nut with the machine faced side onto the spindle.

Assemble the nut on the spindle as described above.

Remove the relief.

Re-assemble the nut.

Turn the nut by 180° and re-assemble it as described above.
